Homework Help: Algebra 1

Posted by Tamir on Sunday, July 18, 2010 at 4:54am.

Hello. I am having a bit of trouble understanding the following

"Solve by Graphing.

3x + y = 5
-2x + 3y = 4"

I know you can't see the graphing on this site, but I would really appreciate it if someone points me in the right direction in how to do this.

put both equations in slope intercept form:

y= -3x+5
y=2/3 x+4/3

check those.

Now graph each. What is each y when x is zero?
what is y when x is 3?

draw lines representing each equation. THe solution is the common point, where they intersect.
